Pyotraumatic dermatitis is an acute, rapidly developing surface bacterial skin infection that occurs as a result of self-inflicted trauma. These lesions are created when the animal licks, chews, scratches and rubs a focal area of skin in response to an itchy, painful stimulus. Because the lesions are warm to the touch, they are often called “hot spots.”
Why is My Dog Getting Hot Spots?
Hot spots are usually a seasonal problem that become more common when the weather is hot and humid because fleas are the most common irritating stimulus. Other causes of hot spots include allergies, tick bites, burrs, mosquitos and ear infections. Hot spots are common in dogs, especially in thick-coated, long-haired breeds. They are rarely seen in cats.
What Does a Hot Spot Look Like on a Dog?
- The circular lesions often appear as hot, red and moist areas. They occur most frequently on the trunk, tail base, lateral thigh, neck and face of the dog.
- Some hair loss over the area occurs as lesion progresses.
- Intense itching (pruritus) quickly makes the issue worse and more painful.
Dog Hot Spot Treatment
The underlying cause of hotspots on dogs should be identified and removed for successful treatment. If the spots are caused by fleas, we can take the necessary steps for dog flea control. If they are caused by allergies, we can treat the allergies.
- Carefully clip the hair over and surrounding the lesions to allow the spots to dry. If lesions are large, sedation may be helpful.
- The lesion will be sore, so gentle cleansing with Vet Basics® ChlorConazole™ Shampoo is important.
- Applying a medicated spray to remove the itch is essential to resolving hot spots. Using Pramoxine Anti-Itch Spray on lesions twice daily eliminates scratching and treats the lesion. Use Vet Basics® ChlorConazole™ Wipes for skin folds or hard-to-spray areas of the face.
- Avoid medications that will dry or sting. Stinging draws attention to the site and increases self-trauma from licking or rubbing. Alcohol-containing products should be avoided.
- Prevent your pet from biting, licking or scratching the affected area.
How to Prevent Hot Spots on Dogs
If the underlying cause of the canine hotspot can be identified, preventing hot spots can be easy by simply managing the cause—controlling fleas, cleaning the ears, treating allergies, etc. Other methods of prevention include keeping a pet’s hair trimmed short during the summer and giving regular medicated baths. Keeping long coats well groomed also helps prevent hot spots.
Will a Dog Hotspot Go Away on Its Own?
- Lesions may be slow to heal, but gentle cleansing of the area on a daily basis will soothe the area and speed recovery.
- Owners should wash their hands after treating an infected animal. Although human infections are rare, the microorganism could present a danger to owners who are immunosuppressed.
